Rheological non-isothermal mechanistic investigation on the curing of glycidyl azide polymer with solid nanofillers

The effects of ammonium perchlorate (AP) and graphene oxide (GO) on the curing of glycidyl azide polymer (GAP) were investigated. The rheological parameters of GAP crosslinked by bispropargyl succinate (BPS) were investigated by rheometry instrument. The curing kinetics by the differential isoconversional method revealed that AP (1 wt%) increased the apparent activation energy from 72.98 to 76.41 kJ mol(-1). However, the presence of GO (0.1 wt%) catalyzed the curing of GAP/triazole by decreasing the apparent activation energy to 62.86 kJ mol(-1). The physical models revealed that the addition of GO changed the cure mechanism of GAP/BPS as it acted as new nucleation sites. The Fourier-transform infrared (FTIR) and X-ray photoelectron (XPS) results also showed that chemical groups on the surface of GO reacted with the hydroxyl groups of GAP, which changed the curing mechanism of GAP/BPS and improved the tension strength of the propellant by 104%.

Scandium-catalyzed highly selective N-2-alkylation of benzotriazoles with cyclohexanones

A scandium-catalyzed highly N-2-selective alkylation of benzotriazoles with cyclohexanones has been developed, providing straightforward access to a series of N-2-alkylated benzotriazoles featuring newly formed tetrasubstituted carbon centers in high yields with excellent regioselectivities. The key to the success of this reaction is using Sc(OTf)(3) as the catalyst. Typically, this protocol is also well compatible with 4-aryl-1,2,3-triazoles.

Efficient copper-catalyzed tandem oxidative iodination and alkyne-azide cycloaddition in the presence of glycine-type ligands

Tandem oxidative iodination and alkyne-azide cycloaddition reaction has provided one of the most widely used methods for preparation of 5-iodo-1,2,3-triazoles. However, stoichiometric copper salts are involved in this type of reaction in order to enhance the reaction effectiveness, which caused some problems related to toxic metal contaminations and less sustainability. In this paper, we described that a copper-catalyzed (10 mol%) tandem oxidative iodination and alkyne-azide cycloaddition could be completed in the presence of the newly-found glycine-type ligands with low-cost Nal as the iodine resource. In the novel reaction system, a wide range of terminal alkyne, organic azide and inexpensive iodide could react effectively in one pot to give structurally diverse 5-iodo-1,4-subsitutied 1,2,3-triazoles. Natural product derivatives and alkynyl pyridines that hardly react under traditional conditions could also be transferred smoothly to the target products for the first time. (C) 2020 Elsevier Ltd.

Synthesis and characterization of biologically important quinoline incorporated triazole derivatives

Triazoles are well recognized in literature for their significant biologically active heterocyclic compounds. Also the quinoline nucleus found in several natural products shows a varied biological activity. Keeping in the view of these observations, a novel series of 6/7/8-substtuted-2-[(5-((4-chlorophenoxy)methyl)-4H-1,2,4-triazol-3-yl)thiolquinoline-3-carbaldehydes and 6/7/8-substituted-2-[(5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio]quinoline-carbaldehydes were synthesized by the condensation of 5-(4-chloro phenoxy methyl)-2,4-dihydro-1,2,4-triazole-3-thiones and 5-(pyridin-3-yl)-4H-1,2,4-triazole-3-thiols with 6/7/8-substituted-2-chloro quinoline-3-carbaldehydes. The new series were established by Mass, NMR and IR spectroscopy and were also screened for their antimicrobial activities. A few of the novel compounds exhibited tremendous bioactivities compared to that of normal drug. (C) 2020 Elsevier B.V. All rights reserved.

Vibrational properties of 1D-and 3D polynuclear spin crossover Fe(II) urea-triazoles polymer chains and quantification of intrachain cooperativity

The vibrational dynamics of the iron centres in 1D and 3D spin crossover Fe(II) 4-alkyl-urea triazole chains have been investigated by synchrotron based nuclear inelastic scattering. For the 1D system, the partial density of phonon states has been modelled with density functional theory methods. Furthermore, spin dependent iron ligand distances and vibrational modes were obtained. The previously introduced intramolecular cooperativity parameter H-coop (Rackwitz et al, Phys. Chem. Chem. Phys. 2013, 15, 15450) has been determined to -31 kJ mol(-1) for [Fe(n-Prtrzu)(3)(tosylate)(2)] and to +27 kJ mol(-1) for [Fe(n-Prtrzu)(3)(BF4)(2)]. The change of sign in H-coop is in line with the incomplete and gradual character of the spin transition for the former as well as with the sharp transition for the latter reported previously (Rentschler and von Malotki, Inorg. Chem., Act. 2008, 361, 3646). This effect can be ascribed to the networks of intramolecular interactions in the second coordination sphere of the polymer chains, depending on the spin state of the iron centres. In addition, we observe a decreased coupling and coherence when comparing the system which displays a sharp spin transition to the system with an incomplete soft transition by analyzing molecular modes involving a movement of the iron centres.

Chemoenzymatic route to stereodefined 2-(azidophenyl)oxazolines for click chemistry

Aryl-substituted esters of a racemic diprotected 2-azido-1-alkanol were submitted to the Staudinger/azaWittig reaction in order to assess scope and establish conditions for their cyclization to the corresponding 2,4,5-trisubstituted oxazolines. Following the cyclization study, the (2R,3R)-antipode of the azidoalkanol was obtained in high ee by incubation of the corresponding racemic azidoacetate with pig liver esterase (PLE). The p-nitrobenzoate of the enantioenriched 2-azido-1-alcohol was cyclized by the Staudinger/aza-Wittig to give the corresponding (4R,5R)-disubstituted-2-(4-nitrophenyl) oxazoline. Selective reduction of the nitrophenyloxazoline to the corresponding aminophenyloxazoline using aluminum amalgam followed by direct azidation of the 2-(4-aminophenyl) moiety provided the corresponding (4R,5R)-2-(4-azidophenyl) oxazoline derivative. The azidophenyl oxazoline was reacted with a proven click partner 4-ethynylfluorobenzene under copper/sodium ascorbate mediation to provide the click triazole product in high yield.

1,2,3-Triazole based poly(ionic liquids) as solid dielectric materials

1,2,3-triazole based polyionic liquids (PIL) are an emerging field among polymeric dielectrics in organic electronics. 1,2,3-triazole based PILs can be obtained from poly(4-vinylbenzylchloride) by copper-catalyzed azide-alkyne cycloaddition (CuAAC) ‘click’ reaction. The polymer architecture and the charge of the PILs can be manipulated by choosing a suitable alkyne, azide containing moiety, and by the alkylation of the 1,2,3-triazole group. Thus, we were able to prepare PILs carrying either inorganic (Na+ or Cl-) or the organic counterions 1-butyl-3-methyl-imidazolium (C4mim(+)) or 1-butyl-3-methyl-imidazolium (TFSI-). Metal-insulator-metal capacitors were fabricated and the dielectric properties were characterized through electrochemical impedance spectroscopy. The PILs demonstrated an increase in capacitance density with decreasing frequency, characteristic for the polarization of the polymer layer and electrical double layer formation. Substitution of inorganic counterions with organic counterions improved the transition frequency of the capacitors and the conductivity of the polymers. This was due to increased ion mobility and decreased glass transition temperatures.

A novel synthetic acanthoic acid analogues and their cytotoxic activity in cholangiocarcinoma cells

A novel series of acanthoic acid analogues containing triazole moiety were synthesized through esterification and CuAAC reaction. Evaluation of their biological activities against four cell lines of cholangiocarcinoma cells showed that 3d exhibited the strongest activity with an IC50 value of 18 mu M against KKU-213 cell line, which was 8 fold more potent than acanthoic acid. Interestingly, the triazole ring and nitro group on benzyl ring play very significant role in cytotoxic activity. The computational studies revealed that 3d occupies the binding energy of -12.7 and -10.8 kcal/mol with CDK-2 and EGFR protein kinases, respectively. This result might provide a beginning for the development of acanthoic acid analogues as an anticancer agent.
